Preamplifiers with traditional power supply (LEMO)

Traditional preamplifiers require an external power supply which delivers a supply voltage of either ±15 to ±60 V DC or +28 to +120 V DC. This type of preamplifier is normally connected to a suitable power supply (for example the GRAS Type 12AK) via a 7-pin LEMO plug or to an analyzer with a suitable LEMO connector.

GRAS supplies measurement microphone cartridges and preamplifiers for microphone cartridges separately and was the first in the acoustics industry to bundle the two items! Pick and choose from the wide range of GRAS measurement microphone sets.
